Couple of minor items:
You probably want to have: BuildRequires: libgfortran-devel (you're linking to it)
The BuildRequires: R is correct, but BuildRequires: R-devel may be needed for
other CRAN packages (if they're looking for libR.pc), and it will drag in R as a
dependency. Might not be a bad idea to script it that way to be safe.
You need to mkdir -p %{buildroot}%{_libdir}/R/library before running R CMD
INSTALL into it. :)

libgfortran-devel doesn't exist as such, it is linked automatically
in when linking with gcc -lgfortran/gfortran. A
BuildRequires: gcc-gfortran
is missing however.
Also looking at the log, it seems that during the link gcc
is used and there is a -lgfortran. In my recalling this is not
what should be done, instead gfortran should be used during the
link and -lgfortran should be omitted. This may be for upstream, or
a R bug, however, I don't know exactly.

Tom "spot" Callaway: Is the preferred way of placing devel files in a -devel
subpackage documented anywhere? (I didn't see anything on the topic in the
Packaging Guidelines.) If there is a preferred way of doing it, I'd rather not
guess what it is. :)
Thanks for your help.

I have revised the spec at the aforelinked-to location to fix the problems noted
earlier.
Note that the -devel package is built for the same arch as the main pacakge, but
it contains only .c and .h files, so rpmlint complains that it should be built
as noarch.

Jason, thanks for the ping.
I suspect that momentum on this packaging attempt got lost during the Extras
merge, which occurred around the time of the submission.
I'd like to resume the process. What's the best way to restart it?
Cheers,
Tom

Since it's been quite some time, I'd go ahead and check the package against the
latest R packaging guidelines at http://fedoraproject.org/wiki/Packaging/R, then
put links to the spec and srpm here, and then spot can give it another look.
hopefully spot's still listening and still willing to sponsor you.

Thanks for the re-review. I'll fix the changelog.
I already have an account. I just need cvsextras approval to move forward. :-)
Note: This is the point where things got bogged down last time, so maybe
something is wrong with the state of my account ("tmoertel"). Please let me
know if you find any problems.
Cheers,
Tom
